Book excerpt: You can count on Rick Steves to tell you what you really need to know when traveling in St. Petersburg, Helsinki, and Tallinn. In this compact guide, Rick Steves covers the essential spots of each city, including the Hermitage, the Church of the Spilled Blood, Linnanmäki (a classic amusement park), and Toompea Castle. Take a day trip to the Peterhof, stroll through Kaivopuisto Park, or visit the Kumu Art Museum. You'll get Rick's firsthand advice on the best sights, eating, sleeping, and nightlife, and the maps and self-guided tours will ensure you make the most of your experience. More than just reviews and directions, a Rick Steves Snapshot guide is a tour guide in your pocket. Rick Steves Snapshot guides consist of excerpted chapters from Rick Steves European country guidebooks. Snapshot guides are a great choice for travelers visiting a specific city or region, rather than multiple European destinations. These slim guides offer all of Rick's up-to-date advice on what sights are worth your time and money. They include good-value hotel and restaurant recommendations, with no introductory information (such as overall trip planning, when to go, and travel practicalities).
